Hello,

i would like to ask about this problem: fan cooler in my e6400 laptop doesn't respond to cpu temperature, it runs at 1000rpm speed all the time, even when temperature rises to 95°C (203°F) and then system reduces cpu frequency. I already tried to replace the fan for one from another e6400 (which works great), then updated BIOS (to latest version 34).

Then i found that fn+shift+15324 and fn+r trick, which works great on that other e6400, but with mine laptop it only shows 1000rpm and im not able to change the fan speed (i can change the number in this screen, but fan doesn't respond and after refreshing the screen, it shows 1000rpm again). Is there any way to make it works properly again?

Thank you
